Thunderbolts #14 is a tie-in to the Avengers Infinity event, and it's a cheap one in that.
I don't mean the price, because the issue isn't worth the paper it's printed on, but it has one or two pages at the end of the issue that "somehow" make it part of Infinity.
Basically the entire issue is a lot of exposition and useless dialogue with the Thunderbolts deciding what mission to do next - which has absolutely nothing to do with Infinity except for The Punisher telling the team that the Avengers are now off-world in the aforementioned two pages at the end.
I don't even know where to begin with the art, but it's definitely the type where you are either going to love it or hate it. Obviously, I am with the latter as I actually think Thunderbolts might be a parody of the previous squad as well as the Marvel U. in general. My personal opinion is the art style is the wrong choice for such a book and completely wrong for Marvel.
Thunderbolts #14 brings up recollection of publishers attempting to cash in on the latest fad event, and that is exactly what is going on with this issue.
This one can be skipped entirely, so don't waste your time and money.
